CSR bluecore initial problem

 
hi all
I got a problem while init the csr bluecore4 chip, my toolchain: bluez-3.12, dbus-1.0.2,kernel-2.6.10
#dbus-daemon --system
#hciattach ttyS0 bcsp
#hcid -f /opt/bluez/etc/bluetooth/hcid.conf
#hciconfig 
hci0:   Type: UART
        BD Address: 00:02:5B:00:A5:A5 ACL MTU: 310:10 SCO MTU: 64:8
        UP RUNNING PSCAN ISCAN 
        RX bytes:1128 acl:0 sco:0 events:23 errors:0
        TX bytes:706 acl:0 sco:0 commands:26 errors:0
above is always ok.
but csr chip need to set pskeys and warmreset,so I run bccmd
#bccmd warmreset
#hcitool scan
Scanning
Timeout...

This problem around me for a few days, I cant figure out why the csr chip doesnt work after warmreset.UART0 connect to csr chip, so I choose bcsp config in kernel and choose hci interface(here i am not sure about choosing hci or bcsp while run bccmd?), am i right?
